(9,810 posts)Lab grade nicotine is made from tomato and eggplant leaves. Apparently, it's cheaper to distill nicotine from non-tobacco nicotinoids because they have fewer close-compounds to refine out. (Also, tomato/eggplant leaves have almost no market, so cheap compared to tobacco.)
The last time we ran the geek bench bets (these devices are an adjunct to my research, so we do little experiments whenever we're bored, quibbling, or between funding) Ecig users were blowing 35-60ppm on a saliva cotinine test, while regular smokers blew 250-400. Non-smokers/vapers blow 8-15 (depending on diet, second-hand). People who live with or work in a place that exposes them to second hand for extended periods run 35-60, so slightly elevated, but clearly not smokers. (Cotinine is the long-life metabolite of nicotine, and cotinine tests are much more accurate than a nicotine blood test.)
